· HfCu4

HfCu4 is an intermetallic compound composed of hafnium and copper, belonging to the family of refractory metal intermetallics. This material is primarily of research and specialized industrial interest, valued for its potential in high-temperature applications where conventional alloys reach their performance limits. The hafnium-copper system offers the possibility of combining hafnium's high melting point and corrosion resistance with copper's thermal and electrical conductivity, making it relevant for aerospace, nuclear, and advanced manufacturing environments where thermal stability and oxidation resistance are critical.
